YARN CLEANER Filed NOV. 30, 1954 2 sheeta shaet 2 INVENTOR m H084 C'E L BOW/E 776i W2 v49 ATTORNEYS United States Patent This invention relates to improved pneumatic means for cleaning and for preventing accumulation of dirt and lint on yarn during the spinning, carding or winding thereof.

The primary object of the invention is to provide more eflicient and practical apparatus of this kind, which is simpler in construction, is more easily installed on yarn handling machines, and which can be manufactured in rugged and serviceable forms and installed at relatively low cost.

Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, specific forms of the invention are set forth in detail.

In the drawings:

Figure 1 illustrates an installation of one form of my invention on a textile spinning machine, portions of said machine being shown in section;

Figure 2 is a fragmentary and contracted perspective view showing the yarn cleaning device connected to the drive cylinder of the textile machine;

Figure 3 is a fragmentary enlarged longitudinal sectional view taken substantially on the line 33 of Figure 2;

Figure 4 is a fragmentary enlarged transverse vertical sectional view taken substantially on the line 4-4 of Figure 2;

Figure 5 is a view similar to Figure 1 of a modified form of the invention; and

Figure 6 is a view similar to Figure 2 of the modified form of the invention.

Referring to the drawings in detail, and first to Figures 1 to 4 thereof, portions of a conventional textile spinning machine are shown, including a horizontal spindle rail 10 on which yarn spindles 12 are mounted to rotate about vertical axes, and are driven by endless belts 14 which are trained over drive pulleys 16 carried by the spindles and over a horizontal driving drum or cylinder 18 which extends the length of the machine in spaced parallel relation to the spindle rail 10. Machines of this kind are conventionally provided with a rail 20 above the rail 10 on which are mounted conventional ring travelers 22 by means of which yarn Y is guided onto the spindle terminals S. The foregoing structure is conventional and forms no part of this invention except in combination therewith.

In the form of the invention shown in Figures 1 to 4, a horizontal supporting rail 24 is attached to the inner side of the spindle rail 10, as indicated at 25, and extends therealong, on which are mounted longitudinally spaced upstanding brackets 26 having openings 28 in their upper ends around which extend lateral annular flanges 30 in spaced concentric relation to the openings. Antifriction bearings 32 are mounted in the bearing housings 34 defined by the flanges 30 and the brackets 26 for a purpose hereinafter described. Carried by the supporting rail 24 intermediate the ends thereof is a pedestal 36 having on its upper end a tubular head 38 which is axially aligned with the openings 28 in the brackets 26. Extending laterally inwardly from the head 38 is a nipple 40 which communicates with the interior of the head, as shown in Figure 3. Bearing bushings 42 are threadedly engaged in opposite ends of the head 38 and align axially with the bearings 32 of the brackets 26.

Extending through and rotatable in the bearings 32 and in the bearing bushings 42 is an air pipe 44 which is parallel to the cylinder 18 of the textile machine. This air duct is provided with longitudinally spaced and longitudinally elongated discharge openings or slots 46 which extend between opposite sides of the head 38 and the opposite ends of the air pipe. The portion of the air pipe 44 within the head 38 is provided with longitudinally elongated, circumferentially spaced air receiving openings 48. Stop collars 50 are secured to the air pipe 44 at opposite ends of the head 38 and bear against the bushings 42 to hold the air duct in proper position in the head, and other collars 51 are secured on the pipe 44 and engage the bearings 32 in the bearing housings 30 on the brackets 26. Threadedly engaged with the nipple 40 of the head 38 is a tube 52 which is connected to the discharge conduit 53 of a suitable blower 54 carried by the machine and having a drive pulley 56. An endless belt 58 is trained around the cylinder 18 and around the blower drive pulley 58 so that as the cylinder 18 rotates, the blower 54 is operated to force air into the head. Obviously, air forced into the head 38 passes through the intake slots 48 in the pipe 44 and flows longitudinally through the pipe 44 and is discharged through the discharge slots 46. In order to assure uniform distribution of air discharged through the slots 46 in the vicinity of the machine, a drive pulley 60 is secured to the air pipe 44 at a convenient location, and an endless belt 62 is trained over the pulley 60 and the cylinder 18 so that the air pipe 44 is rotated as the cylinder 18 is rotated.

By mounting the air pipe 44 to rotate adjacent the spindles of the textile machine, it will be evident that air issuing from the slots 46 will blow away any lint or dirt which might tend to collect on the yarn Y. Because of the sweeping action of the air issuing from the rotating pipe 44, the atmosphere in the immediate vicinity of the yarn Y will be cleared of any debris.

In the modified form of the invention, illustrated in Figure 5, a row of longitudinally spaced upwardly ex-- tending brackets 64 is mounted on the inner side of the spindle rail 10 in any suitable manner, and secured, as by U-bolts 66' t0 the upper ends of the brackets 64 isa horizontal longitudinal air pipe 68 having a longitudinal spiral row of longitudinally spaced air discharge openings 70 extending therethrough.

Secured to the inner end of the spindle rail 10 and extending inwardly therefrom is a horizontally extending bracket 72 carrying a standard 74 which supports at its upper end, as by U-bolts 76, a conduit 78 having on one end a T 80 having a head 81 into whose opposite ends, ends of the air pipe 68 are introduced and having a standard 83 to which the conduit 78 is connected. Connected to the conduit 78 at the end thereof remote from the T 80 is the discharge 85 of a blower 82 which, as illustrated in the drawings, is supported on the horizontal bracket 72. The blower has a drive pulley 84 which is operatively connected to the cylinder 18 by means of an endless belt 86. It will thus be seen that as the cylinder 18 is rotated about its longitudinal axis, air will be forced into the air pipe 68 and be discharged through the openings 70. Opposite ends of the air pipe 68 are closed by caps 88 and similar caps 90 close opposite ends of air pipe 44 of the device of Figures 1 to 4.

In the form of the invention shown in Figures 5 and 6, it will be evident that the blower 82 will be driven as the cylinder 18 is rotated and forces air into the air pipe 68 through the conduit 78 and the T 80, so that air will be discharged in a spiral pattern from the air pipe 68 in the region of yarn spindles so as to cause any lint or other foreign matter to be dispelled from the vicinity of the yarn Y.

While in the foregoing there have been shown and described preferred embodiments of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed herein.
